[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The utility model provides a paper pressing wheel adjusting device for packaging printing, such as Figure 1-Figure 6 As shown, the pressure roller adjustment device for packaging printing comprises:

[0036] A top plate 110, wherein a first sliding unit 210 and a second sliding unit 220 are provided below the top plate 110;

[0037] A driving rod 300 , wherein the driving rod 300 is connected to the first sliding unit 210 and the second sliding unit 220 ;

[0038] A mounting seat 120, wherein the driving rod 300 is disposed on the mounting seat 120;

[0039] The first sliding unit 210 and the second sliding unit 220 are both provided with connecting rod assemblies of the same structure, and a pressure roller 400 is arranged between the connecting rod assemblies. When the driving rod 300 pulls the first sliding unit 210 and the second sliding unit 220 to move, the pressure roller 400 changes height under the driving of the connecting rod assembly;

[0040] In the present application, the pressure roller adjustment device for packaging printing is mainly used for the purpose of pressing and guiding in the packaging printing process, and is usually required to be assembled on the packaging printing equipment. After selecting a suitable area, the top plate 110 and the mounting seat 120 are installed on a preset plane. After the assembly is completed, the control and adjustment can be directly performed on the driving rod 300. The control direction of the driving rod 300 is perpendicular to the direction of the pressure roller 400. Generally speaking, the feed port is kept parallel to the pressure roller 400, and the driving rod 300 can be extended from the feed port to reduce the operation of the top plate 110 structure inside the equipment, so as to reduce the difficulty of adjustment of the pressure roller adjustment device for packaging printing;

[0041] A first slideway 111 and a second slideway 112 are provided below the top plate 110;

[0042] The first sliding unit 210 includes a sliding platform 211, a traction rod 212 and a fixed seat 213. The sliding platform 211 is slidably connected to the first slideway 111 on the top plate 110. The fixed seat 213 is fixed on the top plate 110. One end of the traction rod 212 is connected to the sliding platform 211. The other end of the traction rod 212 passes through the fixed seat 213 and is connected to the driving rod 300.

[0043] The connecting rod assembly is composed of a first connecting rod 214 and a second connecting rod 215. One end of the first connecting rod 214 is hinged to the sliding table 211, and one end of the second connecting rod 215 is hinged to the fixed seat 213. The first connecting rod 214 and the second connecting rod 215 are also hingedly connected. The hinge point of the first connecting rod 214 and the second connecting rod 215, the sliding table 211 and the fixed seat 213 form a triangle and cooperate with the traction rod 212 to form a fixed block mechanism.

[0044] The pressing roller 400 is mounted at the hinge point of the first connecting rod 214 and the second connecting rod 215, and the traction rod 212 is connected to the driving rod 300, and the driving rod 300 completes the height adjustment operation of the pressing roller 400;

[0045] Here, the driving rod 300 is composed of a connecting rod 310, a bearing seat 320 and a screw rod 330. The end of the screw rod 330 is assembled on the bearing seat 320, and one end of the connecting rod 310 is connected to the first sliding unit 210 and the second sliding unit 220 respectively. The bearing seat 320 and the screw rod 330 are arranged on the side of the connecting rod 310 away from the first sliding unit 210 and the second sliding unit 220. The screw rod 330 is assembled on the mounting seat 120, and the mounting seat 120 is fixed on a preset plane. The mounting seat 120 is provided with a screw hole adapted to the screw rod 330, so when the screw rod 330 rotates, it will pull the connecting rod 310 away from or close to the mounting seat 120; the screw rod 330 is assembled on the bearing seat 320 using a bearing structure, so the rotation will not affect the connecting rod 310, and the screw rod 330 can only rotate by itself. Under the limited traction of the mounting seat 120, the connecting rod 310 is away from or close to the mounting seat 120 during rotation;

[0046] In this embodiment, when the feed inlet area of ​​the printing device does not have the conditions for the screw 330 to extend out, that is, the baffle blocks the screw 330, the mounting seat 120 can be removed, and an axial hole is opened on the baffle, and the screw 330 is assembled in the axial hole on the baffle. The feed inlet side is mostly an open area, and the adjustment operation is also convenient and not easy to interfere with the operation of other components.

[0047] As a preferred implementation in this embodiment, a hinge ring is provided between the first connecting rod 214 and the second connecting rod 215 to complete mutual hinge connection, and the pressing roller 400 is assembled in the hinge ring through a bearing structure; in the fixed block structure, when the traction rod 212 moves horizontally, the height of the hinge point of the first connecting rod 214 and the second connecting rod 215 will be driven to change, so the height of the pressing roller 400 located at the hinge point will also change accordingly, thereby meeting the adjustment requirements of the pressing height;

[0048] In this embodiment, the first sliding unit 210 and the second sliding unit 220 have the same structure, one end of the pressing roller 400 is connected to the first sliding unit 210, and the other end is connected to the second sliding unit 220, and the first sliding unit 210 and the second sliding unit 220 are synchronously driven by the driving rod 300, and the pressing roller 400 completes the height adjustment action under the support of the first sliding unit 210 and the second sliding unit 220;

[0049] As a preferred implementation in this embodiment, the traction rod 212 is composed of a front guide rod 2121 and a rear sleeve 2122. The front guide rod 2121 is nested and assembled on the inner wall of the rear sleeve 2122. A spring 2123 is also provided in the rear sleeve 2122. The spring 2123 allows the front guide rod 2121 and the rear sleeve 2122 to be elastically connected.

[0050] In this embodiment, the structure of the spring 2123, the front guide rod 2121 and the rear sleeve 2122 allows the traction rod 212 to be changed from a rigid rod structure to an elastic rod structure, which can increase the toughness of the height adjustment process and avoid the rigid contact between the pressure roller 400 and the packaging paper 500, which may easily cause damage to the packaging paper 500;

[0051] Preferably, the diameter of the front guide rod 2121 is slightly smaller than that of the rear sleeve 2122. A limit ring is provided at the insertion port of the rear sleeve 2122, which cooperates with a clamping ring provided at the end of the front guide rod 2121 to prevent the front guide rod 2121 from slipping out of the rear sleeve 2122. The spring 2123 acts as an elastic member. When the pressure roller 400 is in rigid contact with the packaging paper 500, the pressure roller 400 will be pushed upward. At this time, the spring 2123 will be deformed to make the sliding table 211 move away from the fixed seat 213. At this time, the overall length of the traction rod 212 will be extended.

[0052] Here, the rear sleeve 2122 is fixed on the sliding platform 211, and the front guide rod 2121 passes through the guide hole provided on the fixing seat 213 and is connected to the connecting rod 310;
